BREAD-SLICER.

SPECIFICATION forming part of Letters Patent N0. 783,465, dated Febraary 28, 1905. application filed August 80,1904. Serial No. 222,726.

To all whom it may concern:

Be itknown that I, GUsrAF R001, a citizen of the United States, residing at Tilly Foster, in the county of Putnam and State of New York, have invented certain new and useful Improvements in Bread-Slicers, of which the following is a specification.

This invention has for its object to improve the machine disclosed in Patent No. 756,413, issued to me April 5, 1904, and is directed more particularly to the spring interposed between the pressure-plate and the cutter-lever and to the connections of said spring with said parts.

The invention provides for varying the tension of the spring and for adjusting the distance between the connections of said spring with respectively the pressure-plate and attaching projection of the cutter-lever when said parts occupy a given position.

The invention relates to the novel features and details of construction,which hereinafter will be more particularly set forth, illustrated, and finally embodied in the subjoined claims.

In the accompanying drawings, forming a part of the specification, Figure 1 is a longitudinal section of a bread-slicer such as disclosed in my prior patent herein referred to, showingtheapplication oftheinvention. Fig. 2 is a transverse section of the upper portion of the machine on the line in m of Fig. 1 looking in the direction of the arrows. I Fig. 3 is a detail perspective view of the spring interposed between the pressure-plate and cutterlever, showing the clip and the means for connecting its upper end to the standard or projection of the cutter-lever. Fig. 4: is a detail perspective view of the pressure-plate, showing the lower end of the spring and the means for connecting it to said plate.

Corresponding and like parts are referred to in the following description, and indicated in all the views of the drawings by the same reference characters.

The machine in its general construction is substantially the same as disclosed in my patent aforesaid and comprises the hopper 1,

pressure-plate 2, cutter-lever 3, rotary cutter 4, and spring5, the latter connecting the pressure-plate 2 with an extension or standard 6 of the cutter-lever 3.

Inasmuch as the spring 5 and adjunetive parts form the basis of the present invention, they will be set forth in detail hereinafter and form the subject-matter of the claims. The

spring 5 consists of two members or parts 7 and 8, which normally are curved in opposite directions to admit of varying the effective tension of the spring by means of a clip 9 slidably mounted thereon. While it is preferred to form the parts 7 and 8 of asingle, strip of spring metal, nevertheless said parts may be separate and connected in any manner. An eye 10 is provided at one end of the spring,- and an eye 11 is provided at the opposite end of the member or part 7. erably formed at the fold resulting from doubling the spring-strip upon itself. The eye 11 may be provided in any manner and, as shown, consists of a piece of metal doubled upon itself and riveted or otherwise secured to the upper end of the member 7 The clip 9 holds the two parts? and 8 in close contact, as illustrated most clearly in Figs. 2 and 3, the portion of the members 7 and 8 between the eye 10 and clip 9 being in contact, whereas the parts exterior to said clip 9 are upwardly or oppositely curved; The clip 9 embraces the parts 7 and 8 in such a manner as to hold them together and is secured in the adjusted The eye 10 is pref- 5 position by means of aset-screw 12. By mov- 30 ing the clip 9 upon the spring the effective tension thereof may be regulated as desired, this adjustment serving to bring more or less of the members 7 and 8 into cooperative relation.

The lower end of the spring is pivotally connected to the pressure-plate 2, preferably by means of a pin 13, which is passed through openings in lugs 14 of the plate 2 and through the eye 10. This construction admits of piv- 9 otal movement of the spring with reference to the pressure-plate as the latter moves with the cutter-lever as well as providing for movement of the spring with the cutter-lever when the pressure-plate is stationary, as when in contact with the bread or other article to be sliced. The upper end of the standard or extension 6, projected from the cutter-lever 3, is slotted, as shown at 15, and adjustably sup ports a pin 16, which receives the eye 11 at the upper end of the member 7 of the spring. This arrangement provides for pivotal movement of the spring at its upper end, so as to prevent binding.

Adjustment of the pin 16 in the standard or extension 6 provides for a greater range of movement of the pressure-plate and admits of adapting the machine for different sizes of loaves of bread or articles to be sliced. Adjustment of the clip 9 upon the members 7 and 8 provides for regulating the tension of the spring, so that the loaf or article to be sliced may be held with a greater or less force, as may be required.

Having thus described the invention, what is claimed as new is- 1. In a machine of the character described, and in combination with a hopper, a cutterlever provided with a cutter and a pressureplate, a spring pivotally connected at opposite ends to respectively the pressure-plate and cutter-lever, and comprising oppositelycurved portions, and a clip slidably mounted upon the spring to bring more or less of the spring members into contact whereby the tension of said spring is varied, substantially as set forth.

2. In a machine of the character described, and in combination with a hopper, a cutterlever provided with a cutter and pressureplate, a spring pivotally connected at oppositeends to respectively the pressure-plate and cutter-lever and comprising oppositelycurved portions, means for bringing more or less of the spring members into contact for varying the tension of the spring, and means for varying the distance between the pivotal connections of said spring with respectively the pressure-plate and cutter-lever when said parts occupy a given position, substantially as set forth.

3. In combination, a hopper, a pressureplate, a lever provided with a cutter and having a slotted extension, a pinadj ustably connected with said extension of the lever, a spring comprising members having portions oppositely curved, means for bringing more or less of the parts of the spring into contact for varying the tension, and means for pivotally connecting opposite ends of a member of the spring with respectively the pressureplate and the pin applied to the extension of the aforesaid lever, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
